How could a disgusting human such as yourself have the Inferna Copula, the ring that carries his living soul? Out of everyone that had possessed it, even Strickler who blasted Impure Changeling was better than a human being.
Ever since Jim had slipped the ring out of Strickler's possession, he had entrusted it to you, a human being he had befriended along the way of his Trollhunter quests. While you were not eager to have the ring, it still helped immensely to keep it safe and close. In a way, you were like Morgana, using him as an assassin. But rather than killing the Trollhunter, he was aiding them under your command.
Disgusting! He would crush this human with his skeletal claws if he had his way. But he can't harm the user that wields his soul. So he stews in his anger, reluctantly obeying your command.
However, he wasn't the only one feeling the same way. You were rather reluctant to hold onto the ring under Jim's pleas. While you trust your friends, you were not at all prepared to have such a responsibility of keeping Angor Rot at bay.
"Aaugh! When I get my hands on you, I will crush your skull!" Angor Rot yelled out as he wrung his hands at your face. "Your very human face in pain will be the greatest victory for me!"
You rolled your eyes as you looked around the forest, having to keep Angor Rot hidden away in a cave as you tried, and you mean to try, to get him to loosen up information about how to defeat Bular for Jim's sake. He's not one to give up, even as you try to give out verbal orders, even threatening the ring on your finger.
